STAND FOR ItEOVING-PICTURE MACHINES.

Application filed July 3, 1916.

To all whom it may concern."

Be it known that T, Penn; 1%. GoNsKY, a subject of the King of England, residing at Edmonton, in the Province of Alberta and Dominion of Canada, have invented certain new and useful Improvements in Stands for Moving-Picture Machines, of which the following is a specification.

The invention has for an object to give a stand having all the desirable advantages in such stands, including rigidity, strength, and compactness, while at the same time giving marked advantages in enabling the stand to be quickly adjusted as to height, by an extremely simple operation. it further important aim is to give a construction in such stands which will be adapted to be manufactured at a low cost, and which will be adapted to shipment in compact form, and which will be quite light.

It is also a purpose to give a construction of sectional stand which can be easily assembled in a short space of time.

A very important aim of the invention is to enable the raising and lowering of the table portion of such a stand, by the manipulation of a worm shaft, while at the same time making the stand so as to be supported normally upon four legs, and attain the maximum rigidity with rapidity of adjustment.

Further advantages in the invention will appear, from the construction and arrangement hereinafter shown and described, the invention lying in the combination, relation and construction of the parts, and the drawings, wherein- Figure 1 is a side elevation of the stand.

Fig. 2 is an end elevation thereof.

Fig. 3 is a perspective view of the base section of the stand.

Fig. 4c is a plan view of the stand.

There is illustrated a stand comprising a base shown in Figs. 3 and 4 in detail, made in two parts, a front part 10 and a back part 11.

In the present instance the stand carries a housing 12, accommodating certain winding and rewinding devices, necessitating a particular form, and the frame 10 andll is formed with a downwardly oflset portion 13, to accommodate the shape of the housing. The sections 10 and 11 are each substantially rectangular in plan and of open construction, having smoothly finished vertical faces at the inner sides adapted to be Patented Apr. 24;, 1917. Serial No. 107,380.

secured in close abutment by means of nuts and bolts 14: at each end engaged through suitable cars 15 formed on the frame pieces.

The front section 10 centrally of its forward part is formed with an enlargement 16, at the upper side of which there is formed a circular recess through which projects the worm screw 18, engaged slidably through the frame, and having a suitable collar 19 thereon to support it in the frame, as illus trated in Fig. 1. Atthe outer corners the frame pieces are provided with integral clamping straps 20 engaged around the tubular shanks 21 of foot pieces 2 which are split and secured within the straps". The straps are adapted to be clamped upon the shanks by means of bolts 23, as shown. The foot pieces 22 comprise castings fitted in the lower ends of tubes comprising the shank portions 21.

The screw 18 is operated in the present in stance by means of a hand wheel 25 formed or fixed thereon.

Adjustable over the base there is an upper stand portion 26, comprising end frames 27 in two parts, and a side frame 28, also in two parts. The end frames are identical, the parts of the frame 27 each include central angle iron bars 29, shaped to conform to the housing 12, and so located as to aline with the central bars 10 of the base frame the latter being offset downwardly and outwardly of the corresponding parts 10 and 11 at the outer sides of the base frame.

Each frame 27 includes corner pieces 30, the lower parts of which are set in or otherwise aflixed to suitable leg elements 31 extended downwardly and engaged slidably in the tubular shanks 21 of the feet 22 of the base.

The lower angle iron pieces 29 carried by the upper frame are separate from and attached to the end frame 27, as shown at 32. The top of the frame is formed by a suitable table piece 36, secured to the upper triangular piece 3% of the side frame 28, and to the end frames 27 in a suitable manner. The lower part 33 of the side frame is formed with a bearing boss centrally thereof, forming a mounting for the hub pulley 37, and the upper triangular frame 34 is provided with two similar bearings one at each side, in which the pulleys 38 and 39 are respectively mounted.

The screw 18 may be manipulated to raise and lower the upper section of the stand when the set screws 28 are loosened, and as soon as the stand is adjusted as desired, the screws 23 are tightened to hold the stand in rigid position, giving the fullest strength. In this Way, whenever the stand is adjusted the operator is assured that it will remain level, and he will not be required to make measurements to insure equal extension of the legs on opposite sides. Further, all of the corners of the machine may be raised at the same time, whereas in the machines of this character ordinarily, first one corner and then the other must be raised, or one end raised, and then the other, difficulty being experienced in preventing the raised portionsfrom slipping partly downward before the set screws or other fastening devices are secured.

By the construction of the frame described, it is possible to incorporate in the magazine 12 a number of reeling devices, so that the take-up and rewinding equipment for a machine may all be housed within the one casin The construction isalso prising a base frame made in two parts connected together, each part comprising two legs and intermediate frame portions, one of the parts having a worm screw mounted therein; and a top section including two end frames and one side frame, the side frame having a bored and threaded part toreceive said screw for adjustment of the top section upon the base, said top section having legs at each corner slidably engaged with the base section, and means to clamp said legs in adjusted positions.

In testimony whereof I have affixed my signature in presence of two witnesses.

PETER R. GONSKY.
